PIIIIIIP JOHN PARKER, OF BROOKLYN, NEIV YORK.

VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 595,130, dated December7, 1897'.

Application filed February 20, 1897. Serial No. 624,835. (No model.) e

To all whom, it may oon/cern:

Be it known that I, PHILIP J oHN PARKER, of Brooklyn, in the county ofKings and State of New York, have invented a new and Im provedVehicle-llheel, of which the following is a full, clear, and exactdescription.

This invention relates particularly to that class of wheels providedwith pneumatic tires; and the object of the present invention is toprovide awheel with a tire so constructed that a puncture maybe quicklylocated and suitable repairs made.

The invention comprises a tire made in independent sections forming thetread and having means whereby each section may be independentlyinflated or whereby all of the sections or a portion thereoil may beinflated together.

The invention further consists in the construction and novel combinationof parts and details, as will be hereinafter described, and pointed outin the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure l is a side elevation of a vehiclewheel embodying my invention.Fig. 2 is a section on the line 2 2 of Fig. Fig. 3 is a section on theline 3 3 of Fig. 2, and Fig. 4 is a section on the line 4 4 of Fig.

The tire comprises a number of tubular sections l, each made in thesegment of a circle and closed at its ends. These several sections l areplaced upon the rim 2, with adjacent ends closely abutting, so as toprevent the entrance of gravel or like material. Each section has avalve-tube 3 communieating with it. The valve -tubes 3 extend throughopenings in the rim 2 and have outwardly flanged inner ends which engageagainst the inner surface of the sections. The tubes 3 are threaded ontheir outer sides, and nuts 4 engage with these threaded portions tolock the valve-tube rigidly in place. An nteriorly-threaded thimble 5engages with the exterior thread of the valve-tube 3, and these thimblesalso have exterior threads which engage in tapped openings through anair-tube G, extended around the inner side of the wheel-rim. At eachvalve the air-tube G has a series of ports '7, designed to be placed inline with ports 8, extended through the wall of the thimble 5.

lVhen the parts are in the position indicated in Fig. 2, it is obviousthat air pumped into the tube 6 will pass through the ports 7 and S andenter the tire-sections or any de sired number thereof.

The tube 6 will be provided Awith a nipple 9 for engagement with asuitable pump. After inflating the tire or any desired number of thesections thereof the thimble 5 will be screwed down to the positionindicated in Fig. 3, thus cutting oft communication between the tube Gand the interior of the tiresections. By this construction it is obviousthat should one of the sections of the tire be punctured the same may beeasily located and removed and a new section put in its place. As thesesections are comparatively short and light a desired number of extraones may loc carried by a person riding the vehicle.

The sections l will of course be made of suitable rubber or similarinflatable material, and, if desired, an outer covering may be placedover the several sections and laced in the usual manner. As the endclosures 10 of the sections are of soft rubber it is obvious that theair in the sections will cause the ends of adjacent sections to bearclosely together and thus prevent an outward spreading of the ends ofthe sections.

This wheel will be found useful not only for bicycles but for otherwheeled vehiclessuch,for instance,as sulkies, road-Wagons,&c.

The pipe or tube (i has its ends coupled together, so that it may beeasily removed when desired.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A vehicle wheel, comprising a rim, a tire formedof a series of tubular sections having closed ends, an air-tube withinthe circumference of the rim and provided with openings from which portslead into the tube, valves secured in the sections of the tire andprovided with tubes projecting into the openings of the air-tube, andcaps movable on the valve-tubes and provided with ports adaptedtoregister with the ports of the air-tnbe, substantially as described.

IOO

ro cumferenee of the rim and having screwthreaded openings t0 be engagedby the eX- terior screw-threads of the caps, the said airtnbe beingprovided With ports for registering With the ports of the caps,substantially as specified.

PHILIP JOHN PARKER.
